... Out of common experience, we know that any change in velocity must be due to an interaction between an object (a body) and something in its surroundings. An interaction that can cause an acceleration of a body is called a force. Force can be loosely defined as a push or pull on the body. The r ...

Uniform Circular Motion
... Background: An object in uniform circular motion with a radius (r) travels in a circle at a constant speed. Although the speed is constant, the velocity is changing since the mass’s direction of travel is continuously changing. Based on Newton’s second law, we know that where there is acceleration t ...

Forces and the Universe Unit Review: Weight [N] = 4.44 x Weight
... What is a normal force? It is the force of a surface pushing back in response to gravity. Think about it, if your weight is 400 [N] down and you are standing still, then there must be another force pushing back up to balance you out. That upward force by the ground is called normal force. If a book ...
